Abstract
An ear unit and a portable sound device having the same are provided. The ear unit includes a driver unit, an ear housing configured to form an electric part in which the driver unit is mounted and including a bass hole and a flat hole formed in a first surface of the electric part, a rotator including a second surface opposite the first surface and rotatably coupled to the ear housing, and an opening/closing hole provided in the second surface of the rotator to open or close the bass hole or the flat hole according to rotation of the rotator. The flat hole is connected to an inner hole formed in one position inside the first surface so as to form a duct.
Claims18
An ear unit comprising:
- an ear housing including a bass hole and a flat hole formed in a rear surface of the ear housing, the bass hole being larger than the flat hole;
- a driver unit mounted in the ear housing;
- and
- a rotator rotatably coupled to the ear housing, the rotator including an inner bracket opposite the rear surface of the ear housing, the inner bracket having an opening/closing hole configured to open or close the bass hole or the flat hole according to a rotational position of the rotator,
- wherein the ear housing further includes:
- an inner case having a damper layer and an inner hole formed at the damper layer;
- an outer case coupled to an outer surface of the inner case, the outer case having a hole plate, and the bass hole and the flat hole are formed at the hole plate;
- and
- a duct groove formed in an inner surface of the hole plate so as to connect the inner hole and the flat hole.
A portable sound device comprising:
- an ear unit including an ear housing in which a driver is mounted and a rotator rotatably coupled to a rear surface of the ear housing;
- an ear unit wire comprising one end coupled to a side surface of the ear housing;
- a neck-band housing extending in a longitudinal direction, the neck-band housing having a first end configured to allow the ear unit wire to be introduced into or discharged from the neck-band housing;
- and
- a seating portion formed at the first end of the neck-band housing and surrounding an entire upper portion of the ear unit, the seating portion including:
- a seating surface tilted at a predetermined angle relative to the longitudinal direction and contacting with a rear portion of the ear unit;
- and
- a through hole configured to allow the ear unit wire to extend through the seating portion,
- wherein the ear unit, the ear wire unit, and the neck-band housing are provided in pairs,
- wherein the portable sound device further includes:
- a conducting wire configured to electrically interconnect the pair of neck-band housings;
- a pair of wire brackets configured to support the conducting wire, each wire bracket being connected at a first end to a corresponding neck-band housing of the pair of neck-band housings;
- and
- a pair of wire cases, each wire case being configured to surround a corresponding wire bracket of the pair of wire brackets so as to define an external appearance of the portable sound device, each wire case including a plurality of first screw holes configured to enable fastening between the wire case and the corresponding wire bracket, and
- wherein the first screw holes are provided in each of three positions including the first end, a middle portion, and another portion adjacent the middle portion of the corresponding wire bracket.
